Welcome back to Albany County Fasteners - Fasteners 101
I'm Bob and today we're going to speak about, and demonstrate, Uniburr.
This Uniburr is used to chamfer bolts and we're going to test this baby.
So this is the Uniburr+. This Uniburr is supposed to go from 8-32 to 3/4"-10,
according to what their specifying on the literature.
We're going to open this now; take it out of it's package.
They give you a whole bunch of do's and don'ts in the back here.
Pull the bit out. They also give you how you should address the different types of materials
that you're going to be chamfering with their bit.
So they give you grades and speeds and all different things here for you to read. This is the bit.
As you can see it has these three blades that chamfer
the bolt on the edges to allow you to put a nut on.
So I'm going to demonstrate that now.
So this is a 1/4"-20, grade 8 hex cap screw.
That's the first one we are going to try. We're gonna go gradually go up all the way up to half inch.
You can see it chamfered that with no problem.
The nut goes on.
Let's test the next one.
I'm going to test the 5/16" now, grade 8. These are all grade 8 I'm trying.
We're going to test this one. You can see I'm only crawling; they do not recommend high speed.
High speed will burn up the bit
and then you have to throw it out.
Don't run it in reverse it damages the blade.
Same thing. Worked very well.
On it goes...and you'll see here that this is grade 8, you see the markings on the head, those are markings of grade 8.
Gonna try 3/8" now.
Works just fine.
On and off, not too shabby.
Now I'm going to try half inch.
Perfect. Half inch.
Now I'm gonna test stainless steel.
These are stainless steel, 304 /18-8 stainless steel,
1/2"-13.
Perfect. Perfect job.
Did the job. This is stainless, I'll show you this here.
You can see the markings on the head.
Okay those are stainless, 304 / 18-8 stainless, and
the Uniburr.
The Uniburr did the job and i recommend you go get one.
It'll save you a lot of time, a lot of effort. No grinding required.
No filing, no craziness. 1-2-3 you get the job done.
The key to this bit is: do not use any type of high-speed. You have to crawl
when you're applying the bit and you have to have steady pressure.
You have to apply a little bit of pressure to it, not excessive pressure and let the bit work.
Those are the tips I can give you when testing this bit out.
I'm also going to test 5/8" and I'm going to test 3/4"
This is 5/8" Grade 8.
Awesome. Did the job there, so let's see what happens with 3/4".
As you can see, I'm just crawling the bit along.
No high-speed.
There ya go. Can't beat that.
There you go.
